acid/base part 3

In this part of the acids and bases lab, you will test five different solutions (H3PO4, NaH2PO4, Na2HPO4, Na3PO4, and HNO3) with an indicator called BTB (bromthymol blue).

After you have tested each solution, you will be able to see what happened in each solution on a molecular level to cause the color change.
